Abstract
Nicotinamide dinucleotide phosphate oxidases (NOX) control various cellular signaling cascades. In the nervous system, there is recent evidence that NOX-derived reactive oxygen species (ROS) regulate neurite outgrowth, regeneration, and stem cell proliferation; however, a comprehensive NOX gene expression analysis is missing for all major model systems. Zebrafish embryos provide an excellent model system to study neurodevelopment and regeneration because they develop quickly and are well suited for in vivo imaging and molecular approaches. Although the sequences of five NOX genes (nox1, nox2/cybb, nox4, nox5, and duox) have been identified in the zebrafish genome, nothing is known about their expression pattern. Here, we used quantitative PCR combined with in situ hybridization to develop a catalog of nox1, nox2/cybb, nox5, and duox expression in zebrafish during early nervous system development from 12 to 48 h post-fertilization. We found that expression levels of nox1, nox5, and duox are dynamic during the first 2 days of development, whereas nox2/cybb levels remain remarkably stable. By sectioning in situ hybridized embryos, we found a pattern of broad and overlapping NOX isoform expression at 1 and 1.5 days post-fertilization. After 2 days of development, a few brain regions displayed increased NOX expression levels. Collectively, these results represent the first comprehensive analysis of NOX gene expression in the zebrafish and will provide a basis for future studies aimed at determining the functions of NOX enzymes in neurodevelopment and regeneration.
